Keyboard Input Special Keys Use the ESC key to cancel all current actions and return to the Command: prompt. Press the ENTER key following all keyboard input. You also complete many commands by pressing ENTER. Pressing the SPACEBAR is equivalent to pressing the ENTER key and is often easier to use. Pressing the SPACEBAR or ENTER at the Command: prompt repeats the last command used. Pressing the UP and DOWN arrow keys will cycle through previous commands used. The TAB key is especially useful to navigate in a dialog box. You should use the TAB key to move from field to field. Be careful not to press ENTER.

Tabs: Identifies the purpose and name of the control panel. Panels: Contains groups of related tools associated with the selected tools. More tools: Click and hold the down arrow to display more tools and options in the selected panel.

To turn specific tabs/panels on or off, right-click in the ribbon and select Tabs/Panels.

Command Window The command window is normally located at the bottom of the application window and docked between the drawing area and status bar. Whether you enter a command manually at the command line or click a command tool on a toolbar, all commands are passed through and evaluated by the command line.

Working with Files Drawings are created and saved in the DWG drawing file format. To access this data, you must learn how to create a new drawing, save a drawing, and open these file types. Use the Quick Access toolbar to create, open, and save new drawings.

Displaying Objects When you use the software, you draw all objects at full scale. Sometimes you need to view the whole drawing, sometimes just smaller details. To assist you in viewing different areas of the drawing, there are a number of zoom and pan tools. You can easily magnify small areas of your drawing to provide a closer view or shift the view to a different or larger part of the drawing.

Displaying Objects Zoom Tools Zoom tools help to assist you in viewing different areas of the drawing to get a closer view. Pan Tools You can reposition the centre of your view on the drawing by using the Pan command.
